Migrating an ASP application to IIS 6

Hi,

We have a large IIS application (ASP)
It is written in a combination of ASP (old, not ASP.NET) Javascript,
VBScript (Some client side, some server side) and VB DLLS.

It is all based on an SQL Database

What kind of incompatibilities will it have with IIS 6.0

I realise this is a big question and that I'm not supplying all the
data, but, I would be glad for any quick pointers, or where I can find
specific info.

Does IIS 6.0 support old ASP, or does it only support it in the IIS 5
compatibility mode?

I use ASP/IIS session to manage user information, is this behaviour
affected?

I would like to avoid working in comaptibility mode, is that at all
possible without completly re-writing my code to be ASP.NET?

Thanks

99% of things will work fine. You are best of checking the IIS6 Resource
Kit, because that explains the things that will not work in IIS6 Worker
Process Isolation mode, and you can evaluate that against what you are
currently using.

One thing to be aware of is that IIS6 (by default) unloads unused
application pools if there is no activity for xx minutes (I think it's 120).
If you are storing dynamic data in application variables (eg number of
visitors) you will lose that information when the application unloads
(unless you persist it). You can turn this behaviour off if you want.

Classic ASP is fully supported on IIS6 in all modes. As Ken notes, the
different process model presents some initial challenges understanding the
implications, but they should mostly be resolvable since IIS5 Compat Mode is
like a special case of the more generic IIS6 Worker Process Isolation
Mode -- only one AppPool, no web garden, no recycling of any sort, including
idle/periodic, has a AppPoolId of LocalSystem, and process is named
"inetinfo.exe".
